Most magical girl anime aren't nowhere nearly as popular as Sailor Moon, but you can check out the original one called Sally The Witch or something, which was also made by Toei. Also check out Pretear if you like and this is the anime that I watched on cable TV ages ago. Never heard of Majokko Tickle, Lalabel, Miracle Girls, Magical Emi, Nurse Angel Ririka SOS, PreCure, Ultra Maniac, Magic User's Club or Magical Angel Sweet Mint, but you can watch that too.

Though not exactly an anime, you can also watch W.I.T.C.H., which is like an animated Harry Potter, but girlier. Want another one? then watch The Cosmopolitan Prayers too.
